Superposition of three dimensional homology models of rice CYPs and template structures. a Structures of HmCYP51 (dark khaki), OsCYP51G1 (sky blue) and OsCYP51G3 (gray). Heme molecule is shown as sphere representation. Two VFV molecules are shown by ball-stick model. b Close-up view of the substrate (two VFV molecules surrounded with cyan mesh) environment. The substrate recognition sites were identified based on the alignment with template structure and shown by stick model. c Structures of AtCYP74A1 (dark khaki), OsCYP74A4 (sky blue) and OsCYP74A5 (gray). Heme molecule is shown as sphere representation. 13(S)-HPOT molecule is shown by ball-stick model. d Close-up view of the substrate (13(S)-HPOT molecule surrounded with forest green mesh) environment. The substrate recognition sites were identified based on the alignment with template structure and shown by stick model
